Sr. Manager, Data & ML Engineering - Publishing Platform

Riot engineers bring deep knowledge of specific technical areas but also value the opportunity to work in a variety of broader domains.  We work with both new and current technology, creating innovative solutions to overcome high-volume obstacles and to deliver player value.  As a Senior Manager of Software Engineering, you’ll own and deliver important features and model best practices within the team. 

As a Senior Manager for Data & ML Engineering on the Publishing Platform team, you’ll lead the strategy, culture, and execution behind ML and data systems powering personalization, social experiences, and matchmaking across Riot. You’ll manage a multi-disciplinary team of MLEs and DEs to build scalable, player-impacting systems—from recommendation models to real-time data pipelines—while upholding standards for fairness, performance, and reliability.

• Lead, mentor, and grow a high-performing team of Machine Learning Engineers and Data Engineers, modeling a player–coach leadership style.
• Own the technical strategy for personalization, matchmaking, social systems, and real-time player state.
• Set architectural standards for modeling frameworks, feature platforms, data pipelines, real-time systems, observability, testing, and reliability.
• Oversee ML systems for recommendations, social discovery, and matchmaking with strong Responsible AI practices (fairness, bias detection, explainability).
• Guide teams in advanced modeling approaches such as embeddings, graph ML, two- tower architectures, and reinforcement learning.
• Improve data producer maturity with clear telemetry, schema standards, and medallion (Bronze → Silver → Gold) data quality.
• Provide hands-on technical leadership through architecture reviews, deep design sessions, debugging critical incidents, and unblocking complex modeling problems.
• Shape experimentation strategy, ensuring rigor, power, and trustworthy measurement across large-scale personalization and matchmaking experiments.
• Partner across the matrix (Product, Game Teams, Research, DS, Central Tech, Insights) to align on use cases, standards, sequencing, and long-term platform vision.
• Evolve real-time data systems, streaming architectures, feature pipelines, and ingestion frameworks with strong security, privacy, and compliance discipline.
• Influence platform roadmap by collaborating closely with ML Platform, Data Platform, and Central Tech teams to ensure scalable and unified data and ML foundations.

• 10+ years leading Data/ML Engineering teams, with demonstrated experience managing senior ICs (P4/P5).
• Proven track record building large-scale ML/data systems (personalization, ranking, recommendations, social graph, or matchmaking).
• Deep expertise in data architecture, distributed systems, and ML productionization (feature platforms, real-time pipelines, observability).
• Strong organizational leadership: influencing across teams, defining standards, and driving multi-quarter programs.
• Excellent people leadership: mentoring, coaching, giving feedback, and building engineering culture.

• Experience in gaming, large-scale personalization, or social graph systems.
• Familiarity with Responsible AI, fairness methodologies, or safety considerations.
• Experience with large-scale experimentation platforms and cross-surface measurement.
• Demonstrated ability to provide clarity, direction, and calm in ambiguous, fast-changing environments.
